I-valve yenaliti yensimbi engenasici i-valve eguquguqukayo ye-universal valve steel eyenza izimo zobuchwepheshe

Kungani i-valve yenaliti iyi-valve engalungiswa, ngoba i-spool ye-valve yenaliti iyikhoni ebukhali kakhulu, njengenaliti efakwe esihlalweni, yingakho igama. Inokusetshenziswa okubanzi, njengebanga lokusika lokusika ilangabi, ukulungisa i-knob yokushisa kwelangabi yi-valve yenaliti.
Ivalvu yenaliti yensimbi engenasici enembile ukusebenza kahle kokugeleza. Umzila wokugeleza we-valve yenaliti uqondile ngefomu, ukuze ukugeleza kwe-medium kungasadingeki ukuphenduka, ngokwezinga elikhulu kunciphisa amathuba okufakwa okuphakathi. Ngakho-ke, ifaneleka kakhulu i-viscosity ephezulu, ukumiswa, i-pulp nezinye izindawo zemidiya ezingcolile.
I-Precision Stainless Stainless Neliti valve 2 ukusebenza okukhulu:
1. Ukusebenza kokusika: Ukusebenza okuhle kokusika kwe-valve yenaliti. Esinye sezici ezibaluleke kakhulu ze-valve yenaliti ukuthi ukuxhumana phakathi kwe-spool ye-spherical kanye nendawo yokuhlala kusesimweni sokuxhumana, okunciphisa indawo yokuxhumana futhi kunciphisa izinga lokuvuza kwe-valve. Okwesibili ukuthatha izinyathelo ze-lining, ezifana nomthofu we-lining, i-aluminium yocingo, amapulasitiki wobunjiniyela be-lining, i-raber yemvelo ye-lining kanye nezinhlobonhlobo zokukhethwa kwerabha yokwenziwa.
2, anti-ukugqwala ukusebenza: engagqwali inaliti inaliti umzimba ukuvimbela ukugqwala, ikakhulukazi ukukhethwa okulungile materials. Nakuba ulwazi lokuvimbela ukugqwala lucebile kakhulu, akulula ukukhetha okulungile, ngoba inkinga yokubola iyinkimbinkimbi kakhulu. Ubunzima bokukhetha impahla yomzimba we-valve yukuthi ayikwazi nje ukucabangela inkinga yokugqwala, kodwa futhi kufanele icabangele ukucindezela nokumelana nokushisa, kungakhathaliseki ukuthi umnotho unengqondo, kungakhathaliseki ukuthi ukuthengwa kulula nezinye izici.
Amaphoyinti enaliti enaliti ukuze anakwe: [Indlela yokufaka: ukukhweza eceleni noma ukukhweza phezulu ngokuzithandela]
Ivalvu yevalvu yenaliti yokulungisa kufanele ihlolwe ngaphambi kokufakwa, iplate yevalvu kufanele ihambisane nezinhlinzeko zamanje zikazwelonke ze-“Universal Valve Mark” GB 12220. Ukuze i-valve ingcindezi yayo yokusebenza ingaphezu kwe-1.0MPa futhi idlala indima yokusika epayipini elikhulu, ukuqina nokuhlolwa kokusebenza okuqinile kufanele kwenziwe ngaphambi kokufakwa, futhi i-valve efanelekayo ingasetshenziswa. Ukuhlolwa kwamandla, ingcindezi yokuhlola izikhathi eziyi-1.5 ukucindezela okuzisholo, ubude besikhathi abukho ngaphansi kuka-5min, igobolondo le-valve, ukupakisha kufanele kuqeqeshwe ngaphandle kokuvuza. Ukuhlolwa kokuqina, ingcindezi yokuhlola izikhathi eziyi-1.1 zokucindezela okuzisholo; Ubude besikhathi sokuhlolwa buhlangabezana nezidingo ze-GB 50243.
Ububanzi bokusebenza: uhlobo oluvamile: lufanele ingcindezi ephansi nephakathi, azikho izidingo ze-anticorrosion zesici zohlobo lwe-vacuum: ifanele izinga lokushisa, izinga lokushisa eliphakeme kakhulu, umfutho ophansi, ophakathi nendawo nophezulu, azikho izidingo ezikhethekile ze-anticorrosion ngesikhathi sohlobo lokuvimbela isithwathwa.
Izimo zobuchwepheshe ze-carbon steel forgings yevalvu evamile (ezimbili) Izimbobo zokwelashwa kwesithando somlilo ngamunye kufanele zibe isivivinyo esiqinile, uma izinsimbi ezifanayo zokwelashwa kwesithando somlilo zihlanganisa izinombolo zesithando somlilo esigingqikayo ezingaphezu kwezimbili, inombolo ngayinye yesithando somlilo esigoqekayo kufanele ibe isivivinyo esiqinile. Uma ama-forgings amancane kakhulu, akunakwenzeka ukwenza amabhulokhi amancane okuhlola ukuhlolwa kwe-tensile kuma-forgings noma ukuthatha wonke amabhulokhi wokuhlola ahambisana nesiqondiso esiyinhloko sokuguquguquka, futhi akunakwenzeka ukusetha isethi yamabhulokhi okuhlola okukhanga aphezulu, khona-ke u-1% wenqwaba noma izingcezu eziyi-10 (thatha inani elincane) lingakhishwa ukuze kuhlolwe ubulukhuni. Ukuhlolwa kwengcindezi kuzokwenziwa ngemuva kwe-NDT futhi kuzokwenziwa kancane kancane. Iyunithi yokuqamba izoba nesibopho ngekhwalithi yokufogina kokuhlola.
Uxhumano: jikelele valve carbon steel forgings izimo zobuchwepheshe (I)
Indlela yokuhlola
Ukuhlolwa kwe-tensile
I-forging ngayinye yokwelapha ukushisa izohlolwa ngokushuba. Uma ama-forging anokwelashwa okufanayo kokushisa ahlanganisa izinombolo zesithando somlilo esigoqekayo ezingaphezu kwezimbili, inombolo ngayinye yesithando somlilo esigoqekayo izofakwa ekuhlolweni okuqinile.
Ngaphansi kwesimo sokwelashwa kokushisa kwe-intersample, iphutha lokushisa lingaphakathi kwe-14℃ yenhlabathi, futhi kunemishini yokurekhoda ephezulu nephezulu, inombolo yesithando somlilo esigoqayo ihlangene, futhi ukuhlolwa okuqinile okukodwa kuphela kuyadingeka.
Indlela yokuhlola eqinile izokwenziwa ngokuvumelana nezinhlinzeko ze-GB/T 228.
Uma ama-forgings amancane kakhulu, akunakwenzeka ukwenza amabhulokhi okuhlola amancane kakhulu okuhlolwa kwe-tensile kuma-forging noma ukuthatha wonke amabhulokhi wokuhlola ahambisana nesiqondiso esiyinhloko sokuguquguquka, futhi akunakwenzeka ukusetha isethi yokuhlolwa kwe-forging ephezulu. amabhlogo, bese kuthi i-1% yenqwaba noma izingcezu eziyi-10 (thatha inani elincane) ingakhishwa ukuze kuhlolwe ubulukhuni.
Ukuhlolwa kokuqina
Indlela yokuhlola ubulukhuni be-Forgings ngokuya nge-GB/T 231.1.
Ukuhlolwa komthelela
Indlela yokuhlola umthelela we-Forgings ngokuya nge-GB/T 229.
Ukuhlola okungabhubhisi
Ukuhlolwa kwe-ultrasonic kanye nezindlela zokuhlola izinhlayiya kazibuthe zokubumba kuzokwenziwa ngokuhambisana nezinhlinzeko ze-GB/T4730.
Ukuhlolwa kwengcindezi
Indlela yokuhlola ingcindezi yokufakwa kwengcindezi izokwenziwa ngokuya nge-GB/T 13927.
I-pressure forgings kufanele ihlolwe ngemuva komshini ukuze kuqinisekiswe ukuthi akukho ukuvuza.
Umthetho wokuhlola
Izinto zokuhlola kanye nenani lokufogiwa kwebanga ngalinye kucaciswe kuThebula lesi-5.
Ithebula 5 Ukwenza izinto zokuhlola
Uma imiphumela yokuhlolwa kwezakhiwo zemishini ingahambisani nezinhlinzeko zeThebula 4, ukwelashwa kokushisa kuzophinde kuphathwe ngokuvumelana nezinhlinzeko ze-3. 3, futhi isampula yesampula izokwenziwa ngokuvumelana nezinhlinzeko ze-3.5, kanye nokuhlolwa. izokwenziwa ngokuhambisana nezinhlinzeko ze-5.1. Kodwa-ke, inani lokwelashwa kokushisa kabusha akufanele lidlule izikhathi ezimbili.
Ukuhlolwa kwengcindezi kuzokwenziwa ngemuva kwe-NDT futhi kuzokwenziwa kancane kancane. Iyunithi yokuqamba izoba nesibopho ngekhwalithi yokufogina kokuhlola.
Imfuneko ye-oda
Ithebula le-oda noma uhlu lwemibuzo luzobandakanya okuqukethwe okulandelayo:
a} umdwebo wokubumba umkhiqizo, onetafula nobulukhuni, ukubekezelelana, inombolo yebanga lempahla nezinye izidingo;
b) Inqubo yokubumba yomphakeli kanye nomdwebo wokubumba (ugunyazwe u-Demander uma kunesidingo);
c) Ukwelashwa kokushisa nezinye izidingo kungaxoxiswana ngazo yizo zombili izinhlangothi.
d) Izidingo zokwamukelwa kanye nokuqukethwe okufanele kwengezwe.
U-Demander uzokwazisa iyunithi yomgunyathi phakathi nesikhathi esishiwo kunkontileka uma ithola udoti ohlelweni lokuhlaziya umkhiqizo noma ukwenziwa komshini. Uma kungekho ukuhlinzekwa, akumele kudlule izinsuku ezingama-30.
Ukukhohlisa okuhlongozwayo ukuba kuchithwe kuzogcinwa izinsuku ezingu-30 kusukela ngosuku lokuthunyelwa kombiko wokuhlola, lapho iyunithi yokukhohlisa ingase icele ukuhlolwa kabusha.
Maka nesitifiketi sekhwalithi
Ngemuva kokuthi ama-forging aphumelele ukuhlolwa, uphawu lokufaneleka kufanele lufakwe. Okuqukethwe uphawu kuhlanganisa:
a) Ibhukwana lasefekthri noma ilebula yefekthri,
b) Ikhodi yezinto;
C} ikhodi yokwelapha ukushisa;
d) Isikhathi sokwenza umlomo;
e) Uphawu lomhloli.
Ukuze uthole ama-forging anesisindo esincane namamaki anzima, amamaki angasetshenziswa esikhundleni, kodwa amamaki kufanele abekwe endaweni engathinti ukusetshenziswa kwe-forgings.
Ama-forging azolethwa ngesiqiniseko sekhwalithi esiqinisekisa ukuthi ikhwalithi yokukhohlisa ihlangabezana nezimfuneko zaleli zinga.
